@ballsystemlord  So you are mentioning the user space support of the cameras.
Good question! Actually, the deb packages in Ubuntu are ported from the buildroot
repository in github.com/rockchip-linux, where the gstreamer and camera-engine-rkisp
are contained. You can check it out for reference.

@hsedidin
Performance issue depends on the context.
Both cameras use different MIPI controller with 2 lanes,
the bandwidth not being a problem.
The preview using gstreamer is smooth.

i tried to use an other image ( the last one : FIREFLY-RK3399-UBUNTU18.04-GPT-20190216-1136.img)
look like it's not working i get the following error when i do the sudo bash dual-camera-setup.sh :
E: Unable to locate package libdrm-rockchip1

i tried to continue but it end up in an other error :
XCAM ERROR gstrkisp.cpp:699: Can't find controller, maybe use a wrong video-node or wrong permission to media node
Caught SIGSEGV
XCAM ERROR gstrkisp.cpp:699: Can't find controller, maybe use a wrong video-node or wrong permission to media node
Caught SIGSEGV
exec gdb failed: No such file or directory
exec gdb failed: No such file or directory

( the 2 camera are connected to the board and i did the update/upgrade of the board )
a helping hand would be welcome :p

FIREFLY-RK3399-UBUNTU18.04-GPT-20190216-1136.img has preinstalled the debs mentioned in the setup script.
However, the kernel is not built with dual cameras patches.
You can remove 'libdrm-rockchip1' line in dual-camera-setup.sh and rerun.

Or run the following lines only to update the kernel:

  1. wget http://wiki.t-firefly.com/firefly-rk3399-repo/dualcamera/boot.img
  2. wget http://wiki.t-firefly.com/firefly-rk3399-repo/dualcamera/md5sum.txt
  3. md5sum -c md5sum.txt || echo "md5sum check of boot image failed!"
  4. dd if=boot.img of=$(ls /dev/mmcblk?p3)
  5. sync
Copy the code

I tried to update the kernel but after the reboot to have the new kernel take effect, the monitor shows me a black screen :/
I checked that the monitor detect the firefly rk3399, no problem on this side.
To get out of this black screen I have to erase the flash and flash the Ubuntu 18.04

@no_name

Plz try to build the kernel:

   https://github.com/FireflyTeam/k ... le-4.4-rk3399-linux

So that you can bisect the problem.

hey long time no see.

I try to make it work for the laters version but I give up on this one.

I came back to the older version. It work for only one camera. I got an issue when both cameras are connected one of them doesn't want to start :/

Hi,
I'm understanding OV13850 camera entry in the device tree. And I found two different entries in the device tree.
Is anyone can explain the difference between the two camera entries?

1. from ./rk3399-firefly-linux.dts (or) ./rk3399-rock960-ab.dts
        camera0: ov13850@10 {
                status = "okay";
                compatible = "omnivision,ov13850-v4l2-i2c-subdev";
                reg = < 0x10 >;
                device_type = "v4l2-i2c-subdev";

                clocks = <&cru SCLK_CIF_OUT>;
                clock-names = "clk_cif_out";

                pinctrl-names = "rockchip,camera_default", "rockchip,camera_sleep";
                pinctrl-0 = <&cam0_default_pins>;
                pinctrl-1 = <&cam0_sleep_pins>;

                rockchip,pd-gpio = <&gpio2 12 GPIO_ACTIVE_LOW>;
                rockchip,pwr-gpio = <&gpio1 23 GPIO_ACTIVE_HIGH>;
                rockchip,pwr-2nd-gpio = <&gpio1 22 GPIO_ACTIVE_HIGH>;
                rockchip,rst-gpio = <&gpio0 8 GPIO_ACTIVE_LOW>;

                rockchip,camera-module-mclk-name = "clk_cif_out";
                rockchip,camera-module-facing = "back";
                rockchip,camera-module-name = "cmk-cb0695-fv1";
                rockchip,camera-module-len-name = "lg9569a2";
                rockchip,camera-module-fov-h = "66.0";
                rockchip,camera-module-fov-v = "50.1";
                rockchip,camera-module-orientation = <0>;
                rockchip,camera-module-iq-flip = <0>;
                rockchip,camera-module-iq-mirror = <0>;
                rockchip,camera-module-flip = <1>;
                rockchip,camera-module-mirror = <0>;

                rockchip,camera-module-defrect0 = <2112 1568 0 0 2112 1568>;
                rockchip,camera-module-defrect1 = <4224 3136 0 0 4224 3136>;
                rockchip,camera-module-defrect3 = <3264 2448 0 0 3264 2448>;
                rockchip,camera-module-flash-support = <0>;
                rockchip,camera-module-mipi-dphy-index = <0>;
        };

2. from ./rock960-model-ab-linux.dts
        camera0: camera-module@10 {
                compatible = "ovti,ov13850";
                status = "disabled";
                reg = <0x10>;
                clocks = <&cru SCLK_CIF_OUT>;
                clock-names = "xvclk";

                reset-gpios = <&gpio3 29 GPIO_ACTIVE_HIGH>;
                pwdn-gpios = <&gpio3 28 GPIO_ACTIVE_HIGH>;
                pinctrl-names = "rockchip,camera_default";
                pinctrl-0 = <&cif_clkout>;

                port {
                        ucam_out0: endpoint {
                        remote-endpoint = <&mipi_in_ucam0>;
                        data-lanes = <1 2>;
                        };
                };
        };
